To all whom it may concern:

Be it known that we, Mosns Mosnnn, a citizen of the United States, residing at Cinoinnati, Hamilton county, Ohio, and CARL BARTELS, a citizen of the United States, residing at Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Safe Construction, of which the following is a specification.

This invention, pertaining to safe-construction and relatin particularly to the construction of the oors of round-door safes, will be readily understood from the following description taken in connection with the accompanying drawing in which Figure 1 is a rear elevation of a round safe door embodying an exemplification of.

our invention, part of the rear door-member being broken away to expose parts to the rear of it; Fig. 2 a diametrical section of the same in the plane of line a of Fig. 1; and Fig. 3 a section at right angles to the plane of the general structure and in the plane of line b of Figs. 1 and 2.

In the drawing 1, indicates the front doormember of a round door safe; 2, the stepped margin thereof; 3, an annular flange on the rear of the front door-member, the exterior of this flange entering also into the formation of the-marginal steps of 'the door, the front door-member with its flange being integrally formed and preferably formed of manganese steel or other non-cuttable metal, our present invention peculiarly lending itself to the construction of safe doors of such material; f, the circular recess formed in the rear of the door by reason of the presence of the marginal flange; 5, a rabbet formed in the rear of the interior of flange 3; 6, a rear door-member consisting of a cir- ,cular plate of machinable metal whose periph-- ery fits within the rabbet of the flange; 7

lugs projecting inwardly from the flange in front of plate 6, the front surfaces of these lugs being beveled or helically formed, as indicated in Fig. 3, so as to formsomething of the nature of an interrupted screw; 8, hooks projecting from the front face of plate 6 and engaging in front of logs 7,; 9, a circular series of hooks projecting from the rear face of the front door-member and disposed, preferably, about midway -between the periphery and the center of plate 6, the forwardly presenting faces of these hooks having helical surfaces like those of lugs 7;

1-0, hooks, like hooks 8, projecting forwardly from plate 6 and adapted to engage hooks 9; 11, rings projecting rearw'ardly from plate 6 and adapted to serve as the circular boltframe after the manner usual in round-door safes; and 12, a pin assing through plate 6 and to a position in ront of one of the hookengaging members on the front doormember.

The parts are to be so constructed, in an obvious manner, that when plate 6, forming the rear door-member, is placed in position in the rabbet of the flange of thefront doormember and then given a partial turn the helical character of the hookingengagements will cause the two door-members to be drawn firmly togethen Then, pin 12, having been fitted tightly to place, prevents the unscrewing of the parts, so to speak, and maintains the two door-members in firm and fixed relationship, pin 12 illustrating merely a typical device for efiecting this maintenance.

Machinable plate 6 while truly a doormember, does not 006 crate with the doorjamb, which door-j am is closed entirely by front door-member 1, the plate thus not being strictly an element of safe closure. The engagement of the periphery of the plate with the rabbet of the front door-member serves in centering the plate, thus bringing the circular door-frame concentric with the front door-member. The plate, having been properly fitted to the front door-member, may be removed and dealt with independently of the front doormen1ber, which latter will generally be of massive construction. The plate, or bolt-frame as it really is, having been removed, may be machined and.

fitted up with its bolts, locks and other accessories, and tested out complete as to the movements of its parts without the necessity of the presence of the front door-member. The front door-member, having been fitted to the door opening of the safe, in the absence of the bolt-frame the boltframe may then be applied in position and firmly secured 'to the front door-member, thus completing the door and its accessories upon its inner face. If,at any later time, it becomes necessary or desirable to materially modify the rear accessories of the door, plate 6, with the parts borne by it, may beremoved from the front door-member without the necessity for un- Q Leanna shipping the heavy door-member and with free of contact with thedoor-jamb, means out detracting in any degree from the comfor centering said platerelati've to the front 30 pleteness of the door as an element in clos- (floor-member a circular series of hooking ing the door-jamb. When the rear plate is lugs 'on the rear portion of the front door- 5 replaced upon the front door-member, or member near its periphery, hooking lugs when a substitute rear plate is placed upon projecting from the front of said plate and the front door-member, there need be no adapted to be engaged with the lugs of the 35 j refitting of the rear plate with reference to front door-member by an angular motion of the door-jamb, for the reason that the rear the plate relative to the front door-member,
